Ok, I did a search and couldn’t find a definitive answer.
I see that people have used the universal bracket for this application. Cost doesn’t make sense for me using them just for some boards. Has anyone made something themselves that work? Any in the bed solutions that work?
You can get 80/20 parts from multiple vendors, but I’ve found that tnutz was the fastest and most consistent. The side piece you’re asking is an end plate, which can also be found on tnutz.
Here’s a parts list:
(x1) 10 Series 1x2 bar (don’t recall the length). Ends tapped for 1/4.
(x2) 6 hole end plate
(x4) Stainless 1/4 bolts and washers
(x4) GFC T-Nuts
(x1) Prinsu Maxtrax Mount
Things to note:
Get access holes pre-drilled. Allows for easier accessory install (don’t have to mount and dismount), and it allows for any water build up to be drained.
